  • why does backbone not send the delete?

    - by Nippysaurus
    I have a very basic backbone (sample) application which just creates and destroys model items. When the model is created the object is persisted with a POST to the web server, but when the model is destroyed there is no DELETE sent to the server? Any idea why this might be? very basic model: window.User = Backbone.Model.extend({ urlRoot: 'users' }); my test code just to create and delete the model: var model = null; $(".add").click(function(){ if (model == null) { model = new window.User; model.set({name: 'meeee'}); model.save(); } }); $(".remove").click(function(){ if (model != null) { model.destroy(); } }); The JSON response when creating the model seems good too:

  • Can not use keyboard on unity

    - by ikhsan
    Dear Ubuntu Community, currently I am using Ubuntu 14.04, and few hours ago, an update notifier prompted to install an update.

I tried to logout (mouse is working properly), and login again, try starting onscreen keyboard, but still have no luck, system still doesn't respond to the key press. I tried to login in console, and keyboard working well, tried to install xfce, and keyboard also working properly, keyboard also working properly when login to unity as guest, it only not working when I login using my account. I also try to reset unity config via unity-tweak-tool --reset-unity , but still no luck any suggestion to resolve this?

  • Switching Javascript Function states

    - by webzide
    Dear experts, I would like to implement a API of Javascript that sort of resemble a light switch. For instance, there are two buttons on the actual HTML page act as the UI. Both of the buttons have event handlers that invokes a different function. Each function have codes that act like a state, for instance. button1.onclick=function (){ $("div").click( //code effects 2 ) } button2.onclick=function (){ $("div").click( //Code effects 2 ) } I the code works fine on the surface but the 2 state functions overlap. the effects is going to take place for the rest of the way until the next reload of the document. Basically what I want to achieve is that when 1 button is clicked, it will switch "OFF" the state of function invoked by the other button and vice versa. Thus, the effects achieved are unique are not overlapped. Is there anyway to achieve this or could any experts point me to the right direction. Thanks in advance.

  • dismissViewControllerAnimated completion block presenter view and modal view flow

    - by Patricia LaRue
    I did find an answer to this title and I did do a little research but I'm still not getting the flow. Here is what I want to happen: 1) click a button on the presenter view to open a modal view. 2) retrieve some value and click a button to close the modal view....sending the value to the presentor view and execute a method. I get that this works like a callback but I still can't figure out where to put the callback stuff. So, how exactly do I do this? A) In the presentViewController completion block, should I include the presenter view method to execute when modal view is completed? Or: B) In the modal view's dismissViewControllerAnimated completion block, should I include the presenter view method to execute when modal view is completed? Can somebody help me with some sample code? Or at least help me get the flow of which block to put the code in? Thank you, P

    - by Jambo
    I am working with Twitter widgets with the following script- <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <input type="button" value="Run Function" onclick="test();" /> <script> function test() { new TWTR.Widget({ version: 3, type: 'profile', rpp: 8, interval: 30000, width: 315, height: 340, theme: { shell: { background: '#333333', color: '#ffffff' }, tweets: { background: '#000000', color: '#ffffff', links: '#4aed05' } }, features: { scrollbar: false, loop: false, live: false, behavior: 'all' } }).render().setUser(document.getElementById('TextBox1').value).start(); } When using the function test(); in the button click it is ocming up with the error - Error: Unable to get value of the property 'value': object is null or undefined So it seems like it is not getting to the value at - (document.getElementById('TextBox1').value) I am not sure why it is null if the text box has a value and then the script is run on the button click?

  • JQuery delegate what may cause it to not function

    - by Jafin
    I have a webpage using jquery 1.42 The following 2 segments of code live in my page. $('body').delegate('h2', 'click', function() { $(this).after("<p>delegate paragraph!<\/p>"); }); $('body h2').live('click', function() { $(this).after("<p>live paragraph!<\/p>"); }); The live method always works, yet the delegate doesn't fire at all. If I create a trivial page with simple html <body><h2>blah</h2></body> both approaches work. So I'm assuming there is something else going on in my page. With firebug I am seeing no javascript errors, no html errors. and breakpoints on the delegate method definately do not get hit. What else might be the cause of delegate not triggering?

  • Why for only some actions must I call setTarget?

    - by Max Pierce
    For most actions, I just click and drag in InterfaceBuilder to "wire up" a call from some interface object to my code. For example, if I want to know when the user single-clicks a row in a table, I drag a connection from the table's action to my controller's action. But now let's consider the user double-clicking a row. If I want one of my actions to be called when this happens, I need to call not only -[NSTableView setDoubleAction] but also -[NSControl setTarget]. Why? To be clear, I am not asking why Interface Builder doesn't support setDoubleAction. All tools have limitations. I am trying to gain a greater understanding about how and why setTarget doesn't seem to be necessary unless and until I want setDoubleAction to work. Another way to ask this question would be: Why don't I need to do anything in Interface Builder to set the target of the table's (single-click) action?

  • How do I start the GUI (Window Manager?) over VNC?

    - by Maarx
    I have a netbook and a server, to both of which I installed the identical Ubuntu 10.04 LTS distribution. On the server, I had the foresight to install and enable the SSH server before disconnecting the monitor and keyboard and mouse. I then ssh'ed in and enabled the VNC server as well. Now I want the full server experience on the netbook, but when I VNC in, I am greeted with the displayed screen. (names have been redacted) How do I start the rest of the default Ubuntu GUI experience? (the toolbars at the top) ((is that the window manager?))

    I want to open the Application lens in the Unity Dash as the default lens, since I much more open a programm then searching for a wikipedia article, the weather or anything else the home lens offers. Here How do I show the Applications Lens By Default? and here What are Unity's keyboard and mouse shortcuts? are the same questions, but the suggested answers don't work anymore on Trusty. I know that I can open the application lens with Super + A but I just would like to press Super to open it. An alternative would be to only get online suggestions whe partikular asked for them, but even though I just select the application scope in the filter section I get some useles online results. Btw. I don't want to open the online search results in generall, since I just reactivated them to try it out.

  • How can I use spinner setOnItemLongClickListener

    - by elCarda
    Hi, I am trying to make the Spinner behave different way when the user clicked on an item for a long time. I have spinner with some project and I want two things. When the user simple click on an item I want to normal select it. When the user have long clicked on an item I want to show dialog, with options like "Edit item", "Delete item". The first step works well (ofcourse), but when I am trying to do the second task I can not make spinner to generate longClicked event. Here is my code: this.projectSpinner = (Spinner) this.findViewById(R.id.SpinnerProjects); this.projectSpinner.setLongClickable(true); this.projectSpinner.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener(){ public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Toast.makeText( AndroidTimeTrackerMainActivity.this, "Long click", Toast.LENGTH_SHORT).show(); // This toast doesn't show up. return false; } });

  • How to detect for screenreaders/MSAA without focusing the flash movie?

    - by utt73
    I am trying to detect for the presence of assistive technology using flash. When a Flash movie holding the actionscript below on frame 1 is loaded (and screenreader chatting to IE or Firefox over MSAA is active -- JAWS or NVDA), Accessibility.isActive() does not return "true" until the movie is focused. Well, actually not until some "event" happens. The movie will just sit there until I right-click it & show flash player's context menu... it seems only then Accessibility.isActive() returns true. Right-clicking is the only way I could get the movie to "wake up". How do I get the movie to react on it's own and detect MSAA? I've tried sending focus to it with Javascript... can a fake a right-click in javascript or actionscript? Or do you know the events a right click is firing in a flash movie -- possibly I can programatically make that event happen? My Actionscript: var x = 0; //check if Microsoft Active Accessibility (MSAA) is active. //Setting takes 1-2 seconds to detect -- hence the setTimeout loop. function check508(){ if ( Accessibility.isActive() ) { //remove this later... just visual for testing logo.glogo.logotext.nextFrame(); //tell the page's javascript this is a 508 user getURL("javascript:setAccessible();") } else if (x<100) { trace ("There is currently no active accessibility aid. Attempt " + x); x++; setTimeout(check508,200); } } /* //FYI: only checks if browser can talk to MSAA, not that it is actually running. Sigh. if (System.capabilities.hasAccessibility) { logo.glogo.logotext.nextFrame(); getURL("javascript:setAccessible();") }; */ check508(); stop(); My HTML: <embed id="detector" width="220" height="100" quality="high" wmode="window" type="application/x-shockwave-flash" src="/images/detect.swf" pluginspage="http://www.adobe.com/go/getflashplayer" flashvars="">

  • Animations not accepted in animator

    - by Lautaro
    In the official Unity Animator State Machine tutorial video animation clips are dragged out from the assets folder into the animator and dropped. I have a 3D model that i bought online to experiment with that comes with animations. I added a custom made animation as well. These all work well in my demo project. But when i add a animator to the assets and try to drag and drop animations onto it it doesnt work. I get a forbidden-sign as a mouse pointer. I try to add animations through the inspector but that does not work either. The tutorials makes it seem so easy and does not talk anything about what animations can be used. What am i doing wrong?

  • CakePHP: Ajax view problem (nothing in the view showing)

    - by Adim
    I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

  • Creating a ListView/TreeView using Category (Control Panel-Like) View

    - by Andrew Moore
    I currently have an application which uses a regular ListView with groups to show a bunch of modules. I would like to use a Category view. Category view is the new view introduced in Windows Vista for the Control Panel: Is there a third party control or a way (via API) to create a ListView which mimics the behavior of the Windows 7 Control Panel? Categories with icons and action links. Separate events for Category Click and Action Click. One or two column layout Separators between action links or lines EDIT: Seems like Windows is using a TreeView (SysTreeView32) control internally for this.

  • What steps should be taken to make sure your software is usable by disabled people?

    - by Cromulent
    I want to make sure a piece of software I am writing is usable by people with various disabilities such as blindness and an inability to use a mouse and / or keyboard. Unfortunately I have no experience with things such as screen readers or other methods that disabled people use to make using a computer easier / possible. I've never really had much experience with disabilities at all and unfortunately I don't know any disabled people who I can ask. I was wondering what other people do to make sure that their software is available to a wide range of people with varying abilities? This seems to be a subject matter that is often ignored by developers and I think it is a real shame.

  • Launch Rhythmbox using a Keyboard shorcut

    - by palerdot
    I use Rhythmbox all the time in my Ubuntu. Is it possible to have a custom shortcut like Ctrl+R in Ubuntu, which can launch the Rhythmbox window, even if it is playing in the background ? Since, the emphasis of Linux OS flavors is to use keyboards as much as possible instead of mouse, i thought this functionality might tremendously help me in my Ubuntu environment. The Keyboard shortcuts sections asks for a command; So, I'm not able to figure out how to give a custom keyboard shortcut to a program like Rhythmbox. I'm using 12.04 if that helps. Thanks.

  • viewing fbx files in windows via xna 4.0

    - by user17753
    I've made some models in Blender and exported them in Autodesk fbx format. I'm trying to view them using XNA 4.0 Refresh. Loading them isn't much an issue, but I'm not familiar enough with XNA 4.0 to, well basically I want to load in the model at say the origin (0,0,0) world coordinates, and then rotate and/or zoom the camera about the world coordinates origin as well so that I can test the model. Typically the mouse, and maybe some arrow keys for zooming/rotating the camera. Anyways, this seems like a simple task and I shouldn't have to re-invent this, isn't there a skeleton code somewhere for this kind of thing for XNA 4.0? I couldn't find a solid example for this on the web. I found a couple that seemed like they might work for xbox, but I'm trying to do this on windows only. Anyways, just looking to be pointed in the right direction on this one, thanks.
